This report presents statistics on the characteristics of inmates of institutions enumerated in the Eighteenth Decennial Census of Population, taken as of April 1, 1960. All of these statistics are based on a 25-percent sample of the population. The report presents data on the age, color, and sex of persons under care in several types of institutions, for the United States, each State, and each Standard Metropolitan Statistical Area of 500,000 or more, and on color and sex of inmates by Type of Institution for counties and urban places with 1,000 or more inmates. For the United States, the data are also presented by number of institutions of each type, size of institution, type of control, location, year inmate moved into institution, marital status, race, Nativity and Parentage, region of birth, Puerto Rican Birth, mobility status, School Enrollment, Years of School Completed, Year Last Worked, last major occupation group of those employed in 1950 or later, and Veteran Status by period of military service.

In this report, data are presented for the United States in tables 1 to 32, for States in tables 33 to 41, for Standard Metropolitan Statistical Areas of 500,000 or more in tables 42 to 51, and for selected counties and urban places in table 52. Within each type of area, the tables are arranged by type of institution. In General, each table presents data for a given Type of Institution with subdivision by type of control. This arrangement means that the population for which statistics are presented in a single table is relatively homogeneous with respect to age, and thus it is possible to show age in detail suitable for the particular type of institution.

Complete-count statistics on the total institutional population for States, their urban and rural parts, counties, standard metropolitan statistical areas, urbanized areas, and urban places of 10,000 or more are presented in chapter B of Volume I, Characteristics of the Population. Statistics based on the 25-percent sample are presented on resident staff of institutions and on inmates by age, color, and sex, for States, urban and rural, and for Standard Metropolitan Statistical Areas of 250,000 or more, in chapter D of Volume I. Several of the other special reports in the PC(2) and PC(3) series of reports contain additional information on the institutional population 14 years old and over.

Volume IV, Special Reports, Part 2, chapter C, Institutional Population, presents complete-count data on the age, color, and sex of persons under care in each of several types of institutions-correctional institutions, hospitals for mental disease, tuberculosis hospitals, homes for the aged, homes and schools for the mentally and physically handicapped, homes for neglected and dependent children, and other types of institutions for younger persons. These statistics are presented for the United States, regions, and States. For counties and urban places with an institutional population of 500 or more, data on age, color, and sex of the total institutional population are also presented. Additional information on the characteristics of inmates appears in several other special reports comprising Volume IV, notably the report on Employment and Personal Characteristics and the report on Marital Status. Information on the total institutional population for various areas appears in chapter B of Volume II, Characteristics of the Population.

The data shown in the present report represent the full detail printed out by the electronic computer. However, the detail shown for the United States was tabulated separately for each State and its urban-rural parts but was stored on magnetic tape and not printed out. Requests for unpublished data may be made by writing to the Chief, Population Division, Bureau of the Census, Washington 25, D.C., and giving a specific description of the figures desired. Inquiries concerning unpublished data should be transmitted to the Bureau as soon as possible because tape files are not maintained indefinitely.
